The calculus chain

Diagram linking displacement s(t), velocity v(t), and acceleration a(t) with differentiation arrows forwards and integration arrows backwards

In constant acceleration questions you could use SUVAT, but with variable acceleration the acceleration changes with time, so SUVAT usually does not apply. Instead, calculus links displacement, velocity and acceleration.

Variable Acceleration Lesson

  1. AS Level
  2. /Maths
  3. /Variable Acceleration

Step-by-step lessons on Edexcel AS Level Maths Variable Acceleration, covering 11.1 Functions of Time, 11.2 Using Differentiation, 11.3 Maxima and Minima Problems, 11.4 Using Integration, and 11.5 Constant Acceleration Formulae. Each one builds up to exam-style questions. Build fluency in the core algebra, surds and trigonometry topics early, since they underpin the calculus, statistics and mechanics content that follows.
